They call it the blues.....those once in a while "feeling down" moments
Now there are many "blue" moments that are normal. But try and get a head's up (from your doctor or the internet) on what PPD really is. It's good to know the difference between just having the blues and PPD. During those first few weeks get as much help as possible so that you have a little "you time" (even if it's just 10 minutes). Whenever you feel down just try and remember that you are doing your best. If you are not too convinced by that, look at your baby. You are the bestest (if that's a word) and your little one thinks the world of you! Hope that makes you smile.
